基于投入产出模型的钛白粉生产企业经济效益研究

On the Economic Benefit of Titanium Dioxide Production Enterprise Based on Input-Output Model

在硫酸法钛白粉生产的背景下,基于投入产出模型,研究了硫酸法生产工艺中的先进组合对企业经济效益的影响问题。立足于环保和成本,构建了投入产出模型。通过验证得到了该工艺组合对副产物的经济收益,"三废"成本的节约额以及环保成本的降低额。结论表明:在硫酸法钛白粉生产中采用投入产出模型研究企业的经济效益是适用的;该先进生产工艺组合是可行的和可操作的。

For titanium dioxide production, the effect of the latest advanced technological combination in sulfuric acid method on economic benefit is discussed in this paper. The problem is formulated as an input- output model by considering environmental protection and cost. Then, the effect of the advanced techno- logical combination on economic benefits of the by-products, the cost savings of ＂three wastes＂, and the reduction of environmental cost are analyzed. Results show that the proposed Input-Output model is appli- cable to the production of sulfuric acid process. Also, it shows that the technological combination is feasi- ble and operational.
